Fusion of functional magnetic resonance imaging (fMRI) and genetic information is becoming increasingly important in biomarker discovery. These studies can contain vastly different types of information occupying different measurement spaces and in order to draw significant inferences and make meaningful predictions about genetic influence on brain activity; methodologies need to be developed that...
Along with the emergence and development of translational biomedicine, more and more genetic information has been applied in clinical practice. In recent decade, the discovery of genetic biomarkers for cancer prognosis obtains increasing attentions and many methods have been developed. The "element" methods use one or two independent genes to judge the Boolean status of disease. The "set"...
Objective: Study the correlation between some parts of Traditional Chinese Medicine (TCM)'s physical examination elements and the parameters of the renal function. Method: Select 935 samples of TCM four diagnostic and syndrome differentiation information from young healthy examinees, study the correlation between these information. Results: there is extremely significant positive correlation coefficient...
An image watermarking scheme using the previously proposed bit embedding method is developed. To achieve a desired subjective visual quality in the watermarked image, the embedding parameter that is related to both the image quality and the embedding capacity is determined by using a perceptual model. First, based on the properties of the bit embedding method, the perceptual model of two kinds of...
Fault location is important for attitude determination (AD) of satellite which provides better services without any degradation. Firstly, the assumption of statistically independent between 3-axis Euler angles and statistically independent between Euler angles and faults are proposed in this paper. Also it is assumed the fault appears only in one group of sensors and the fault is additive. With two...
Hadoop Distributed File System (HDFS) has been widely adopted to support Internet applications because of its reliable, scalable and low-cost storage capability. Blue Sky, one of the most popular e-Learning resource sharing systems in China, is utilizing HDFS to store massive courseware. However, due to the inefficient access mechanism of HDFS, access latency of reading files from HDFS significantly...
The present study looks carefully at EEG(Electroencephalograph) signals of people after the hypnosis inductions. Subjects were in three different categories of hypnotizability based on Waterloo-Stanford criteria; low, medium and high. Signals recorded during standard tasks of Waterloo-Stanford were applied to study the underlying dynamics of tasks and investigate the influence of hypnosis depth and...
The Stevens Passive Acoustic System allows the detection, tracking and classification of various surface and underwater sources of sound including surface vessels, swimmers, various types of divers, and unmanned underwater vehicles. This system was developed by Stevens in its Maritime Security Laboratory, which was established to support research in the area of Anti-Terrorism and Force Protection...
We study the performance of distributed source coding in large wireless sensor networks obtained with enhanced correlation estimators. Distributed source coding is especially useful when data correlation exists since it tries to remove the redundancy in the information; and dense sensor networks are rich in correlations. Existing results from information theory show that this compression can be executed...
This study presents an empirical analysis of the effects on correlation of the site-to-site transport of ATEs. Four correlation scenarios are presented with permutations of calibration/non-calibration of the testers. The results show that the least number of uncorrelated tests are encountered when there is calibration at the reference tester site, with or without calibration on the target site. Also,...
Traditional coding method used the same prediction structure to encode the multi-view sequences whose correlation are distinctly different. This method eliminated the temporal and spatial redundancy by using multi-references blindly. Although the traditional prediction structures have quite good coding efficiency, it results in the problem of high complexity. So by analyzing the characteristic of...
A pilot-aided integer frequency offset (IFO) estimation scheme robust to the timing offset is proposed for orthogonal frequency division multiplexing (OFDM)-based digital video broadcasting-terrestrial (DVB-T) systems. The proposed scheme first produces correlation values between each continual pilot (CP) and a predetermined scattered pilot (SP), and then, recorrelates the correlation values in order...
In the scalable video coding extension of the H.264/AVC standard, an exhaustive search technique is used to select the best coding mode for each macroblock. This technique achieves the highest possible coding efficiency, but it demands a higher video encoding computational complexity which constrains its use in many practical applications. This paper proposes combined fast sub-pixel motion estimation...
A real time solution of tracking daily lung tumor motion is proposed in this paper in order to achieve an accurate dose delivery for radiation therapy as recently developed cone-beam computed tomography (CBCT) technique is not able to catch tumor motions due to the patient's respiration. We develop a novel GPU-based fast digitally reconstructed radiograph (DRR) generation algorithm which enables an...
We propose an approach to conduct video scene detection especially for travel videos captured by amateur photographers in journeys. The correlation between a travel video and its corresponding text-based travel schedule is discovered. Because scene boundaries are clearly defined in schedules, we segment videos into scenes by checking the discovered cross-media correlation. To make these two modalities...
When the ABS supports mixed mode that is it supports both 16e MSs and 16m AMSs, if we have a Software Defined Radio which supports both 16e and 16m modes, then we can take advantage of the extra preamble available from the other mode to do either fast or robust coarse timing synchronization. For 16e mode, if the signal is weak and cannot synchronize on 16e preamble, the MS can first synchronize on...
This thesis analyzes the characteristics of cold chain logistics and establishes the index system of the location of logistics distribution center. The gray comprehensive evaluation applies gray correlation analysis as well as the AHP and studies the location of cold logistics distribution center with the organic integration of the two methods. Finally it is proved with the combination of the case.
In this paper we present some basic investigations to show the relation between the element correlation of antennas on a common small terminal and the characteristic modes on the chassis excited by those antennas. The results show, that the characteristic of an antenna array is heavily affected by the weighted characteristic current modes of the chassis. The actual mode and its weight, however, depend...
The aim of this paper is to combine curvelets with wave atoms by using the mixed constraints, namely smoothness of semi-norm of decomposition spaces and sparsity. It fully considers the sparse representation of curvelets and wave atoms. Curvelets are an essentially optimal representation of objects which is C2 away from a C2 edge, while wave atoms have a significantly sparser representation of the...
We present beam-based imaging algorithms using back-propagation and MUSIC, utilizing data measured by arrays of point sources and receivers (transducers). In this approach, the measured point-source/receiver data is first converted into a beam-domain data, where the source and the receiver arrays are described by phase-space sets of beam waves. The beam-domain data describes the scattering amplitudes...
